Note
To obtain accurate wheel centring using the cones the centre hole of the wheel must not
be deformed in any way!
The cones are used for balancing van, off-road vehicle and car wheels with centre hole
diameter larger than the diameter of the shaft (40 mm). The following components are
available:
- Ø 40 cone kit for centring passenger car wheels with hole diameter from 42 to 103.5mm;
- Ø 40 cone kit for centring passenger car wheels with hole diameter from 100 to 118.5mm;
- Ø 40 cone kit for centring passenger car wheels with hole diameter from 117 to 173mm;
- adapter disk for centring holes with a rear mating diameter smaller than the flange
diameter. This accessory is generally used in conjunction with the small cone;
- distance ring to use with van and off-road vehicle wheels with centre hole requiring the
use of the large cone.
The centring procedure for a car wheel using the above components is similar to the
procedure indicated for truck cones. Normally it is not necessary to use the wheel lift.
The following parts are also available: universal quick release flange for centring car wheels
without centre hole or with centre hole of smaller diameter than the spin shaft (40 mm).
This accessory is used as follows:
- remove the threaded part of the shaft (threaded hub);
- fit the flange to the balancer shaft and secure it with the flange fixing screw;
- insert the RFS gauge pins into two adjacent fixing holes on the wheel and measure the
distance (fig.7);
- set up the same number of studs on the quick
release flange as there are fixing holes in the
wheel and at the same distance as the distance
measured in the previous step.
Use three studs for wheels with six fixing holes.
- Tighten the nuts on the crank mechanism adjuster
pins until the cranks are adequately clamped.
To obtain correct centring do not tighten the
nuts completely yet. This allows for a certain
amount of adjustment during the following stage
of clamping the wheel to the flange.
- Fit the wheel on the flange and secure it with the
nuts and bushes (if necessary) that are most suitable for the type of hole;
- fully tighten the connecting rod pin nuts.
